Answer:
a = 4
b = 2√3
Step-by-step explanation:
Here, we want to get the missing side lengths
We start by looking at the values that we are given
from the question, a faces the right-angle and is called the hypotenuse; it is also the longest side
b faces the angle given and is also called the opposite
Lastly, the side marked 2 is the adjacent side
Now, the triangle given is called a 30-60-90 triangle
In a 30-60-90 triangle, the ratio of the sides are given as
1: √3:2
Thus, we have 1 as the adjacent
The opposite would be √3 * 2 = 2 √3 = b
Lastly , a = 2 * 2 = 4
Answer:
20 students
Step-by-step explanation:
In order to find the answer, we must find 2/3 of 30 students.
2/3 of 30 students can be found by multiplying the two numbers together.
2/3 * 30 is equal to 2/3 * 30/1
2/3 * 30/1 is 60/3
60/3 is equal to 20
20 students brought their attendance contracts back on Tuesday.
Answer:
0.00005
Step-by-step explanation:
The probability of the stock going up and that of winning in the lottery are independent.
Hence, the probability of both = P(stock going up) × P(winning in the lottery) = 0.5 × 0.0001 = 0.00005
